Salinity changes of à watercourse

Numéro d´article: P1521462

Principle

This experiment shows how the salt that is washed out of an abandoned potassium rock pile drastically increases the salinity of a watercourse, as well as how the salinity decreases only slightly further downstream, and how the salinity can still be measured after the stream has converged into a river.

Benefits

  • Experiment is part of an experiment set with numerous experiments in ecology
  • Universal handheld measurement device can also be used for other measurement parameters relevant in ecology, biology and chemistry
  • Outdoors measurement possible, for mobile use
  • Graphical display of measurement data
  • Data can be saved on SD memory card
  • All data can be transferred onto a computer for data analysis
  • Data analysis software can be freely distributed

Tasks

  1. Measurement of the conductivity of water samples taken at different locations of a watercourse
  2. Compare measurement values and make statements concerning the reasons for the changes
  3. What you can learn about

What you can learn about

  • Groundwater
  • Salinity
  • Fertilizers
  • Anthropogenic factors
